Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints.
A summary of the overall procedure to follow is provided on the following page in the
form of a flow chart.

4. FAULT FINDING PROCEDURE
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from Techline,
●for approval requests when replacing parts for which approval is mandatory,
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the proper tools. IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT

REV COUNTER INSTRUMENT
Fault finding - List and location of components
The rev counter is located on the instrument panel, facing the driver, just behind the steering wheel.
Three versions of the rev counter are available depending on the equipment level:
–“Sport” rev counter graduated up to 8000 rpm.
–Petrol engine rev counter graduated up to 7000 rpm.
–Diesel engine rev counter graduated up to 6000 rpm.

REV COUNTER INSTRUMENT
Fault finding - Role of components
–Rev counter: engine speed signal. The engine speed signal is sent to the rev counter by the injection computer on
the multiplex network.
–Electronic stability program (ESP) indicator light:
The ESP indicator light comes from the ABS and is sent by the multiplex network.
The ESP indicator light is an amber coloured light.
The indicator light is tested for 3 seconds by the rev counter when the + after ignition feed is switched on (only if the
ESP function is present on the vehicle and programmed on the Renault production line or in After-Sales).
This indicator light will only be activated if the configuration LC002 ELECTRONIC STABILITY CONTROL (ESP) is
WITH.
The electronic stability program indicator light gives information about the following statuses of the ESP system:
–Lighting function - dimmer lighting:
The rev counter lights up in accordance with the illumination of the lights and the instrument panel.
The dimmer lighting function is controlled by the instrument panel using the control located under the steering wheel.
The request is sent to the rev counter by the multiplex network. The rev counter varies the light intensity in
accordance with the signal received.ESP system statusRev counter Instrument panel

REV COUNTER INSTRUMENT
Fault finding - Function
System outline
The system is composed solely of an offset rev counter on the instrument panel facing the driver, which incorporates
its own computer.
The function of the “rev counter” system' is:
●To display the "engine speed" signal image in rpm sent by the injection computer on the multiplex
network.
●To identify the traction control system warnings on equipped vehicles.
Depending on the configuration, when the lights are switched on, the rev counter backlighting may vary depending
on the instrument panel backlighting dimmer request, the light signal is sent on the multiplex network by the
instrument panel.
